537 satisfy symbol dependancy in solib.c (core_ops).
538 * target.[ch] conditionalize Mach-specific signals so that they
539 won't show up in non-Mach gdb's!
540 * thread.c: change name of static function "thread_switch" to
541 "switch_to_thread", to avoid conflict with Mach global symbol;

659 * java-exp.y: Combine TRUE and FALSE into BOOLEAN_LITERAL.
660 (Avoids name clash with broken AIX header files.)
662 Sat Apr 19 01:49:37 1997 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
664 * serial.c (serial_log_command): Fix fputs_unfiltered calls.

692 * defs.h utils.c (error warning): Make message be const.
693 * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
694 to hook. Otherwise send it to fputs.
695 * monitor.c monitor.h (monitor_get_dev_name): New function. Does
697 * remote-e7000.c: Remove debugify stuff. Change printf, fprintf
698 to _filtered forms to make output appear in GUIs. Replace all
699 uses of SERIAL_READCHAR with readchar, which has better error
701 * (e7000_parse_device): Add prototype.
702 (readchar): Improve doc. Handle random serial errors.
703 (expect): Disable notice_quit code. It's busted. Remove
704 serial error handling (it's now handled in readchar). Remove
705 remote_debug echoing. That's handled in readchar as well.
706 (e7000_parse_device): Remove serial_flag arg. It's not
708 (e7000_open): Split into two pieces. Second part is
709 e7000_start_remote, and is error protected. Now, when we connect
710 to the target, we setup the initial frame and registers so that
711 the user gets an immediate indication of where the target is.
712 (gch): Remove debug output. That's handled by readchar.
713 (e7000_read_inferior_memory): Handle errors better.
714 (_initialize_remote_e7000): Get rid of `<xxx>' things from
715 command names. They show up when doing completion and confuse
717 * ser-e7kpc.c: Get rid of the DLL's since we can access the device
718 directly from Win32s and Win95. Get rid of debugify crud.
719 * serial.c: Remove debugify cruft.
720 * (serial_logchar serial_log_command serial_write serial_readchar
721 serial_send_break serial_close): Merge common functionality into

787 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
788 (INSTALL_XFORM1): Remove.
789 (install-only): Use $(program_transform_name) directly, rather
790 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
791 (uninstall): Transform name.
793 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>
795 * remote-mips.c (mips_load): Ensure that PC gets updated

800 * procfs.c (notice_signals): fix typo
802 Mon Apr 14 16:25:10 1997 Ian Lance Taylor <ian@cygnus.com>
804 * gdbserver/Makefile.in (INSTALL): Change install.sh to
807 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
809 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
810 since gcc automatically includes it
812 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
814 * procfs.c: Substantial (but incomplete) changes to support
815 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
816 struct now has substructs like struct flt_ctl instead of
817 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
818 map_fd instead of a single fd. Non-sysv4.2mp procfs models
819 still have the structs and multiple fds, but don't use the
820 entire struct and the four fds all point to the same thing.
821 We use PROCFS_USE_READ_WRITE to decide whether to talk to
822 procfs with reads/writes or use ioctl instead. We use
823 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
824 multiple fds or not. PROC_NAME_FMT is split out into
825 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
826 STATUS_PROC_NAME_FMT.
828 (procfs_notice_signals): now a necessary wrapper around
829 (notice_signals): which are the new guts for noticing signals
830 (open_proc_file): gets a new flag arg used in sysv4.2mp to
831 determine whether or not to attempt to open the ctl_fd.
832 (procfs_read_status): new local function, reads procfs status
833 (procfs_write_pcwstop): new local function, writes a PCWSTOP
834 (procfs_write_pckill): new local function, writes a PCKILL
835 (unconditionally_kill_inferior): remove signo since we now
836 just call procfs_write_pckill().
837 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
838 (proc_iterate_over_mappings): the whole function is ifdefed
839 on UNIXWARE to keep things readable.
841 Expanded the syscall_table to include new potential sysv4.2mp
842 members. Note that all ifdefs of UNIXWARE should be eliminated
843 if possible or renamed to describe what's being selected for a
844 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
845 IRIX specific code now also checks it's not UNIXWARE.
847 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
848 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
849 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
850 "/debug/%d" as PROC_NAME_FMT used to be
852 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
854 * mn10300-tdep.c: Almost completely rewritten based on mn10200
856 * config/mn10300/tm-mn10300.h: Likewise.
858 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
860 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
861 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
862 lousy out-of-date clone of remote.c.
864 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
866 * remote.c: Fix problems realized while showering.
867 * (hexnumlen): Add prototype. Use max, not min.
868 * (remote_write_bytes remote_read_bytes): Fix max packet size
869 calculations to properly account for packet overhead. Also handle
870 (probably rare) case where remote_register_buf_size isn't set.
872 * remote.c: Fix doc for `C' and `S' commands to indicate full
874 * (remote_ops extended_remote_ops remote_desc remote_write_size):
876 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
877 Record size of response to fetch registers command, use this to
878 limit size of memory read and write commands.
879 * (push_remote_target): New function to make it possible to have
880 another target switch to the remote target.
881 * target.h: Add prototype for push_remote_target.
882 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
883 for hosts which default to unsigned chars (such as SGI's).
884 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
885 handled automatically in remote.c.
887 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
889 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
890 find_pc_sect_function(), find_pc_sect_partial_function(): new
891 functions for debugging overlays; pc without section is ambiguous.
892 * breakpoint.[ch]: add section pointer to breakpoint struct;
893 add section argument to check_duplicates(); check section as well
894 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
895 breakpoint_thread_match(), bpstat_stop_status()];
896 add section argument to describe_other_breakpoints();
897 use INIT_SAL() macro to zero-out new sal structures;
898 make resolve_sal_pc() fix up the sal's section as well as its pc;
899 match on section + pc in clear_command() and delete_breakpoint();
900 account for overlay sections in insert_breakpoints(),
901 remove_breakpoint() and breakpoint_re_set_one();
902 all this to support overlays where a PC is not unique.
903 * exec.c: change xfer_memory() to handle overlay sections.
904 * findvar.c: change read_var_value() to handle overlay sections.
905 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
906 * infcmd.c: jump_command() warns against jumping into an overlay
907 that's not in memory. Also use INIT_SAL() to initialize sals.
908 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
909 overlay state information; Also use INIT_SAL() to init sals.
910 * m32r-rom.c: modify load routines to use LMA instead of VMA.
911 * m32r-stub.c: mask exit value down to 8 bits; screen out any
912 memory read/writes in the range 600000 to a00000, and ff680000
913 to ff800000 (hangs because nothing is mapped there); fix strcpy().
914 * maint.c: maintenance command "translate-address" supports overlays.
915 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
916 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
917 this constitutes gdb's internal overlay mapping table. Add macro
918 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
919 Add function find_pc_sect_section().
920 * printcmd.c: modify print_address_symbolic() with overlay smarts;
921 modify address_info() with overlay smarts; add function sym_info()
922 to support the INFO SYMBOL command (translate address to symbol(s));
923 modify disassemble_command() to work on unmapped overlays.
924 * source.c: use INIT_SAL() to initialize sals.
925 * symfile.[ch]: change generic_load() to use section's LMA address
926 instead of VMA address, for overlay sections.
927 Add numerous functions for finding a PC's section / overlay,
928 translating between VMA and LMA address ranges, determining if an
929 overlay section is mapped, etc. Add several user commands for
930 overlay debugging. Add support for a "generic" form of automatically
931 reading overlay mapping info from the inferior (based on the default
932 (simple) overlay manager which Cygnus provides as an example).
933 * symtab.[ch]: add functions find_pc_sect_symtab(),
934 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
935 for lookup; modify lookup_symbol and decode_line_1() to use them;
936 modify find_function_start_sal() to account for overlay sections;
937 add macro INIT_SAL() for initializing struct symtab_and_line.
938 * target.c: fix a comment in the declaration of target_ops.
940 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
942 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
943 mips_skip_stub, mips_ignore_helper): New functions for dealing
944 with MIPS16 call/return thunks.
945 (mips_init_frame_pc_first): New function to implement
946 INIT_FRAME_PC_FIRST macro; includes code from old macro plus
947 new code to skip over MIPS16 thunks.
948 (mips_frame_chain): Skip over MIPS16 thunks.
949 * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
950 mips_skip_stub, mips_ignore_helper): Declare.

955 (mips_init_frame_pc): Declare.
956 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
957 to decide if certain library function calls should be ignored.
959 Wed Apr 2 14:16:51 1997 Doug Evans <dje@canuck.cygnus.com>
961 * remote-sim.c (gdbsim_open): Check return code from sim_open.
